I'm building a page with pagination and a filter form (2 GET requests). If
the URL includes both pagination and filter results, something like
`/questions/?page=2&all_questions=on`, it works fine. It also works if it
just has filter results, something like `/questions/?all_questions=on`.
However if it only has the pagination page result, something like
`/questions/?page=1`, no results are shown.
So I figured I need to do something in the views so that if there is only
page number in the URL, a default filter will be given. I know I probably
need to add something to the Try and Except section of pagination, but I'm
stumped as the actual code I need to write.
def questions_index(request):
user = request.user
form = QuestionFilterForm(request.GET or None)
question_list = []
if not form.is_bound:
question_list = Question.objects.all().order_by('-date_created')
if form.is_valid():
if form.cleaned_data['all_questions'] |
(form.cleaned_data['general_questions'] &
form.cleaned_data['location_all_gta']) == True:
question_list =
Question.objects.all().order_by('-date_created')
elif form.cleaned_data['location_all_gta'] == True:
question_list +=
Question.objects.filter(question_type=1).order_by('-date_created')
else:
if form.cleaned_data['general_questions'] == True:
question_list +=
Question.objects.filter(question_type=2).order_by('-date_created')
if form.cleaned_data['location_toronto'] == True:
question_list +=
Question.objects.filter(location='1').order_by('-date_created')
paginator = Paginator(question_list, 15)
# Pagination
page = request.GET.get('page')
try:
questions = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
questions = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of
results.
questions = paginator.page(paginator.num_pages)
### I need to write something here...
except (url has no filter result)
give default filter
return render(request, 'questions_index.html', {'questions':
questions, 'user': user, 'form': form})
